Effects of Time-restricted Hypocaloric Diet in Patients With NAFLD
May 10, 2023 updated by: Aimilia Papakonstantinou, Agricultural University of Athens
Effects of a Time-restricted Hypocaloric Mediterranean Diet in Patients With Non-alcoholic Fatty Liver Disease on Glucose Metabolism (CHRONO-NAFLD Project)
The effects of a time-restricted hypocaloric Mediterranean type diet compared to a conventional hypocaloric Mediterranean type diet on blood glucose metabolism and liver steatosis in people with non-alcoholic fatty liver disease will be investigated.

Detailed Description
The goal of this clinical trial is to evaluate the effects of the time in which food intake is restricted (morning or evening hours or no restriction in time) on glucose metabolism and liver steatosis in the context of a hypocaloric diet plan in 54 patients with non-alcoholic fatty liver disease (NAFLD).
The participants will be divided into 3 groups of 18 individuals each and will be randomly assigned to one of the 3 dietary interventions.
In the first group (control group), participants will be given a weight loss program based on the principles of the Mediterranean Diet (energy deficit of 500 kcal/day with the aim of losing 0.5 kg per week) with the instruction to consume their meals throughout the day, without time restriction.
In the second group (early eaters), individuals will be given a weight loss program based on the principles of the Mediterranean Diet (energy deficit of 500 kcal/day with the aim of losing 0.5 kg per week), and they will be asked to consume all of their meals within 10 hours (between 07:00-09:00 and 17:00-19:00) and refrain from consuming caloric foods and drinks for the remaining 14 hours.
In the third group (late eaters), individuals will be given a weight loss program based on the principles of the Mediterranean Diet (energy deficit of 500 kcal/day with the aim of losing 0.5 kg per week), and they will be asked to consume all of their meals within 10 hours (between 11:00-13:00 and 21:00-23:00) and refrain from consuming caloric foods and drinks for the remaining 14 hours.
Finally, all groups will be instructed to moderately exercise for 150 minutes per week.

Experimental: Early Time-Restricted Feeding Plus Hypocaloric Mediterranean Diet
Early 14:10 time-restricted feeding plus hypocaloric Mediterranean diet

18 patients with NAFLD will be asked to follow an early 14:10 (14 hours fasting and 10 hours feeding) time-restricted (eating between 08:00-18:00) and individualized Mediterranean diet plan with caloric restriction (energy deficit of 500 kcal/day) for 12 weeks
|
Experimental: Late Time-Restricted Feeding Plus Hypocaloric Mediterranean Diet
Late 14:10 time-restricted feeding plus hypocaloric Mediterranean diet
|
18 patients with NAFLD will be asked to follow a late 14:10 (14 hours fasting and 10 hours feeding) time-restricted (eating between 12:00-22:00) and individualized Mediterranean diet plan with caloric restriction (energy deficit of 500 kcal/day) for 12 weeks
